Abstract: A synchronization information sending method, a synchronization information receiving method, a base station, and a communications node are provided. The sending method includes: obtaining, by a communications node, a pulse per second PPS; obtaining, by the communications node, a first time T1 based on the PPS; obtaining, by the communications node, a second time T2 based on the subframe; determining, by the communications node, a first time difference TD 1 based on the first time T1 and the second time T2; obtaining, by the communications node, a second time difference TD 2 based on the first time difference TD 1 and the TA. Different base stations use a same pulse per second PPS as a reference to adjust a sending time, a radio frame number, and a subframe number of a subframe, so that the different base stations are synchronized with each other.

Abstract: The technology of this application relates to a communication method, apparatus, and system. The method includes determining a target transmission requirement of a first node, determining, based on the target transmission requirement, whether to establish a first transmission channel, where the first transmission channel is used to communicate with a second node, and sending a first request message to the second node, where the first request message is used to request to establish the first transmission channel. The method further includes receiving a first response message from the second node, where the first response message is used to confirm establishment of the first transmission channel. In the method, the first transmission channel is dynamically established between the first node and the second node based on the target transmission requirement of the first node, to help flexibly schedule a transmission resource for the first node.

Abstract: A vehicle driving authority transfer method and apparatus are described for assisted driving and automated driving. The method includes checking a status of a system of a vehicle before a driving authority of the vehicle is transferred. The driving authority of the vehicle is transferred only when the vehicle is at a normal status. Therefore, the status of the system of the vehicle is checked before transferring the driving authority of the intelligent vehicle, thereby avoiding a liability dispute arising from a traffic accident caused by abnormality of the status of the system of the vehicle, especially by abnormality of a braking system and/or a steering system closely related to vehicle operability/manipulability, after the driving authority of the vehicle is transferred.

Abstract: Embodiments of the present invention provide a cell handover method and a device. so that the target eNB uses a current serving small node as a user plane serving node after UE is handed over and uses the target eNB as a control plane serving node after the UE is handed over; receiving a handover request acknowledgment sent by the target eNB; and sending offloading configuration information of the current serving small node to the current serving small node, and sending RRC reconfiguration information of the UE to the UE, so that offloading configuration is performed separately by the current serving small node and the UE. This avoids a problem that in a cell handover process, a transmission resource required for transmission increases and a delay is relatively great because the current serving small node forwards a large amount of data to the target eNB.
